Unfortunately, you can’t filter model lines (or detail lines) in Revit. To be honest, I very rarely come across a situation where I actually need to perform this task, I don’t use model lines that often except in families. However for some, it is desirable and whilst you can’t filter them through the usual methods, one work around I use is to simply create ‘purpose built’ line styles.
For example, let's say you are documenting a carpark for a site plan and you are using model lines for the layout. In various other floor plans though, we may want to see these carpark lines for context, but we typically want them faded or greyed out as they are not the focus of the particular drawing. At the moment, you may selecting all these lines and applying an element override, and you may have to do this a few times. There is a better way though using Visibility Graphics.
Start by creating the required line styles; for example, ‘Carpark-Kerbs’ & ‘Carpark-Dashed’.
Now it is just a matter of going to the view in question and modifying these line styles in the Visibility Graphics. In this case, I have overridden the line column with a grey line colour. You could add the change to your view templates too.
